The 39-year-old driver was taken to Lehigh Valley Hospital in Salisbury Township with unknown injuries, Upper Saucon police Chief Robert Coyle said. Depending on the results of a blood test, he could face criminal charges in the crash, the chief said.

There were at least two people home when the crash occurred about 1:21 a.m. in the 2500 block of South Pike Avenue near Upper Saucon's border with Salisbury Township, but none of the occupants were injured, Coyle said.

According to the chief, the vehicle was speeding south on South Fourth Street in Allentown and caught a city police officer's attention. The officer followed the vehicle but did not engage in a pursuit, he said.

By the time the officer caught sight of the vehicle again, the driver had flipped the vehicle and crashed into the house, Coyle said. In addition to striking the home, the vehicle damaged a utility pole and gas line, he said.

No other vehicles were involved in the wreck, the chief said.

The house was evacuated and residents stayed with a neighbor while PPL and UGI crews repaired the damage, Coyle said. The residents have since returned home, he said.

Coyle said he didn't know whether the Allentown police officer activated his overhead lights or siren when he followed the vehicle or how fast the vehicle was going when it crashed.
